How do you configure tomcat to bind to a single ip address (localhost) instead of all addresses?

Several connectors are configured, and each connector has an optional "address" attribute where you can set the IP address.

1. Edit tomcat/conf/server.xml.
2. Specify a bind address for that connector:

   <Connector 
       port="8080" 
       protocol="HTTP/1.1" 
       address="127.0.0.1"
       connectionTimeout="20000" 
       redirectPort="8443" 
     />
   

it's well documented here:

https://cwiki.apache.org/confluence/display/TOMCAT/Connectors#Connectors-Q6

How do I bind to a specific ip address? - "Each Connector element allows an address property. See the HTTP Connector docs or the AJP Connector docs". And HTTP Connectors docs:

http://tomcat.apache.org/tomcat-7.0-doc/config/http.html

Standard Implementation -> address

"For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, this port will be used on all IP addresses associated with the server."
